Most common type of power driven tap is the "spiral point plug tap"; whose cutting edges are angularly displaced relative to the tap centerline.

This feature causes the tap to continuously break the chip and eject it forward into the hole, preventing crowding.

Spiral point taps are ideal for machine tapping of through holes or blind holes where there is enough clearance
beyond the threaded portion to accommodate the swarf. (fine chips or filings of stone, metal, or other material produced by a machining operation)
